Car idles at 500 rpm! ...and....

system · February 23, 2002, 3:11am

This recently started in the last month…I’ll start the car and it will constantly idle at about 500 rpm’s…doesnt move much from there. I Cleaned out the throttle body (It was very dirty) and changed my plugs and wires (The plugs were more than double the gap it was supposed to be at!!) ,but it didnt help. I’m going to check the cap and rotor, pcv valve, and fuel filter. Any other suggestions?

Problem 2: The car had an oil change 2,000 miles ago and the level was 1 quart low. There’s no smoke but the bottom of the engine is definitly leaking from somewhere. Could it be the oil pan gasket? or any other gaskets that seem to go in these cars. (92 RS w/ 120,000 mile) Thanks!

Try just resetting your ecu. That might fix it.

mine idles at 500rpm also… mine also shook real bad and it contiuned to get worse over time. diagnosis: bad front and rear motor mounts. Infact it was so bad they were not even there anymore! changed the motor mounts and the car still idles at 500 but is almost vibration free. And since i got new motor mounts the car seems to “hit” harder when shifting (it’s a good thing).
